Simultaneous assembly on multiple hosts

Hi all,

Is it dangerous have an array assembled on two hosts at the same time?
Say I have servers A and B exporting devices a and b via ATA over
Ethernet or similar to hosts C and D.  If a and b are components of an
array then both C and D automatically assemble the array as soon as
the components a and b are exported but is this safe (on the proviso
that only one of C or D is ever writing to the array at any time and
that there is no write-behind caching above the array device)?

Thank you,

- neil
